Heavy-duty dump truck beds, power shovels, and rock crushers. If you need the official document for certification

One of the most critical aspects of GB/T 16270 is the mechanical performance requirements, which guarantee the steel’s ability to withstand structural loads. The table below outlines the mechanical properties for several common grades. The table below outlines the mechanical properties for

| Element | Typical Limit (Max %) | Purpose | | :--- | :--- | :--- | | | 0.12% – 0.20% | Lower carbon improves weldability. | | Silicon (Si) | 0.60% | Deoxidizer. | | Manganese (Mn) | 1.00% – 1.70% | Strengthens ferrite. | | Phosphorus (P) | 0.025% (for Grade E) | Impurity restricted for toughness. | | Sulfur (S) | 0.015% (for Grade E) | Impurity restricted to prevent cracking. |
